ok i have gained alot of info from everyone lets see about this one want to get a 115hp johnson long 20 to put on 94 trophy 1802 w/ 25 in transom. what would be the best route concerning jack plates. from where the old motor with 25in sets i would only have to adjust 1 1/2 to 2 1/2 inches to keep the cavitation plate between the bottom of drain plug and 2inches up the transom, keeping thhe bullet of the shaft 1 to 2 inches below drain plug.
